Forecasters with the National Weather Service (NWS) Hurricane Center have declared tropical system Nicholas a tropical storm and is expected to become a depression early Wednesday morning moving south of our region.
Heavy amounts of rain are expected for the southern portion of Louisiana as it moves northeastward, with flash flood warnings to those southern and central regions of our state.
For northwest Louisiana, with the current storm track, the seven-day Quantitative Precipitation Forecasts (QPF) is 1 to 2 inches with isolated higher amounts. Some localized flash flooding is possible since this is a tropical system.
NWS indicates this area will be in a Flash Flood Threat Marginal Risk of 5-10% Tuesday through Wednesday. Most of rain is forecast for the area Tuesday into Wednesday with rain chances staying around through the weekend. A Wind Advisory for area lakes is in effect until 5 pm.
Bossier Office of Homeland Security and Emergency Preparedness is monitoring another tropical system that formed off the coast of Africa and is now south of the Cabo Verde Islands.
This system generally moves westward at about 15 mph across the eastern tropical Atlantic Ocean. Over the next five days the system has a 90 percent development probability, but remains too far out to be able to predict what will happen.
